TEHRAN: An Iranian lawmaker claims that President Barack Obama called for direct talks with Iran in a secret letter to the Islamic Republic's supreme leader that also warned Tehran against closing the strategic Strait of Hormuz. Obama administration officials denied there was such a letter. Iran has threatened to close the waterway, the route for about one-sixth of the global oil flow, because of new US sanctions over its nuclear program. Conservative lawmaker Ali Motahari revealed the content of the letter days after the Obama administration said it was warning Iran through public and private channels against any action that threatens the flow of oil from the Persian Gulf. "In the letter, Obama called for direct talks with Iran," the semiofficial Fars news agency quoted Motahari as saying Wednesday. "The letter also said that closing the Strait of Hormuz is (Washington's) red line." "The first part of the letter contains threats and the second part contains an offer for dialogue," he added. Iran's Foreign Ministry spokesman Ramin Mehmanparast confirmed that Tehran received the letter and was considering a possible response. In Washington, an Obama administration official denied that Obama sent a letter to Iran's Supreme Leader Ayatollah Ali Khamenei, saying communication of US views were being delivered through other diplomatic messages. The official would give no further details. The official spoke on condition of anonymity because of the sensitivity of the issue. National Security Council spokesman Tommy Vietor pointed to earlier comments from the Obama administration that noted the US had a number of ways to communicate its views to the Iranian government. He said the US remained committed to engaging with Tehran and finding a diplomatic solution to its larger issues with Iran's nuclear program. Spokesmen have been vague on what the United States would do about Iran's threat to block the strategic Strait of Hormuz, but military officials have been clear that the US is readying for a possible naval clash. Iran's Revolutionary Guard, the country's most powerful military force, says Tehran's leadership has decided to order the closure of the oil route if Iran's oil exports are blocked. A senior Guard officer said earlier this month that the decision has been made by Iran's top authorities. Iranian politicians have made the threat in the past, but this was the strongest statement yet that a closure of the strait is official policy. Iran's regular army recently held naval war games near the vital waterway that were described by hard-liners as part of preparations to close the strait if sanctions are imposed. The Guard is planning major naval military exercises next month in the same region. The US last month enacted new sanctions targeting Iran's central bank and its ability to sell petroleum abroad over Tehran's nuclear program. The US has delayed implementing the sanctions for at least six months, worried about sending the price of oil higher at a time when the global economy is struggling. Closing the strait would have immense world economic impact. Iran is OPEC's second largest oil producer, and oil exports account for 80 percent of Iran's foreign currency income. To Tehran, an oil embargo would be tantamount to a declaration of war that could provoke the Iranian leadership to block the Hormuz strait. At issue is Iran's nuclear program. The US, Israel and others charge that Iran is trying to build nuclear weapons. Their case was bolstered by a report from the International Atomic Energy late last year, citing evidence that Iran was employing methods and equipment used in making bombs. Iran has consistently denied that, saying its nuclear program is peaceful, aimed at producing electric power and isotopes for cancer treatment.
